Answer:
The length of the hypotenuse is 17.
Step-by-step explanation:
I found this out by doing:
15 x 15 = 225
8 x 8 = 64
225 + 64 = 289
Hope this helps you! :)

a trapezoid
equation for area = h(a +b) ÷ 2
so you sub that in
8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120
so the area is 120cm
8
A trapezoid
equation for area = h(a +b) ÷ 2
so you sub that in
6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42
So the answer is 42 inches
9
A kite
equation for area = p× q ÷ 2
so you sub that in
(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3
So the answer is 33 cm
sorry I can't see 10s measurements
20^2 + (x-8)^2 = x^2
x^2 = 400 + x^2 -16x + 64
16x = 464
x = 29 = hypotenuse
Double - Check
29^2 = 20^2 + 21^2
841 = 400 + 441
Answer:
45
Step-by-step explanation:
Answer:
Step-by-step explanation:
2x + 2 + 3x + 6 = 23
5x + 8 = 23
5x = 15
x = 3
3(3) + 6 = 9 + 6 = 15 = BC
